You may have to be careful with this. I believe you will need to review various sets of regulations concerning issues with product safety, e.g. Supply of Machinery (Safety) Regs, Simple Pressure Vessels (Safety) Regs, Electrical Equipment (Safety) Regs, etc, to confirm whether CE Marking is required or exemptions exist.
The DTI has on its website (do a search for CE Marking) various FAQ documents for guidance (e.g. file11288.pdf). The DTI guidance states that for machinery, if you are manufacturing equipment for yourself (even if not intending to be sold, but "taking into service"), it is regarded as "self supply" and the Supply of Machinery Regs apply, hence implies CE marking is needed (although this is not explicitly stated as such).
A DTI guidance doc for Electrical Equipment (Safety) Regs states that electrical equipment must satisfy the requirements of the regs, but CE marking is not required for use in your own premises however.
Simple Pressure Vessels permit some exceptions to CE marking for supply and "taking into service".
Complex equipment that consists of being all of those (machine, electrical equipment, simple pressure vessels, etc) I assume default to having to be CE Marked because of the Machinery Regs. A simple and complete overview of guidance from the regulators would be useful IMHO.
This is an interesting question for educational establishments or manufacturers that have R&D departments constructing and supplying themselves with one or low numbers of equipment, or single prototype equipment pending full scale manufacture and supply to others.
What you need to do for CE marking is highly dependent on the type of equipment. Fundamentally its about risk assessment and assessment against essential health and safety requirements (using harmonised or national standards in the absence of harmonised standards). What you do already probably isn't far off the Conformity Assessment process (and final CE marking), if it is applicable to your equipment. You will be carrying out your risk assessments, under PUWER to determine the residual risks after control measures are applied, and you are probably compiling what could constitute a Technical File listing the components, with drawings, designs, calculations carried out, specs, hazard checklists, literature, involvement of third parties, test reports, etc. You perhaps need to appoint a Responsible Person to oversee all this.
To complete the process you may need approval from an Approved Body, prior to CE Marking. That will depend upon the type of equipment and really the associated risks.
The CE Marking process is generally poorly understood and any additional guidance or comments/corrections would be welcome. The HSE have published research reports from surveys that show significant misunderstandings.
